ICD-10 Code C92.50 – Acute myelomonocytic leukemia, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.50 – Acute myelomonocytic leukemia, not having achieved remission
What it is
C92.50 identifies acute myelomonocytic leukemia that is still active and has not reached remission. Use it when the record clearly states this leukemia subtype and shows no remission status.
Clinical signs
Clinical features vary; refer to documentation. Commonly, acute leukemia presents with marrow failure findings and circulating abnormal myeloid/monocytic cells, but you should code only what is documented.
When to use this code
Use C92.50 when the provider documents acute myelomonocytic leukemia and specifically notes that remission has not been achieved. It also fits cases described as persistent, refractory, or active disease, if the record supports that status. If remission status is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for acute myeloid leukemia without documented myelomonocytic subtype, or when the leukemia is in remission. If the chart does not confirm non-remission, do not assume it.
Coding tip
Look for both the subtype and the remission status in the same encounter note, pathology report, or problem list.
